Darn tactical - NcSTAR Shotgun Barrel/Mag Tube Micro-Dot/Rail Mount

So darn tactical it flew off the front of my shotgun into the AZ dirt, which btw is rock. I thought Id put on tight enough but I guess not. It seems huge at the end of the shotty. If I were to add an ar red dot, it looks stupendous in not an ingenious kind of way. How can I say this, it just isn't for me and i think I'll return it but maybe ill keep it as a fake grenade to be launched of the end. actually it never fell off as I now remember but it went all the towards the front sight and left some marks on my shotty. maybe some extra torque and some red locktite or maybe just blue. Anyway this thing is just barely largish and lots of rail when i just needed two, flashlight and to see if a red dot would work. The holosun hs04 was huge and didn't make it out of the house with the little .20 gauge, embarrassed. 20 gauge Remington . Its only 20$ so ima give it 20 stars-17 stars for the shotty sizing.
